摘要:
采用扩散控制无皂乳液共聚法,将苯乙烯(St),甲基丙烯酸(MAA)和二乙烯基苯(DVB)3种单体进行共聚合反应,制备表面洁净的纳米聚合物交联微球。系统考察了反应温度、引发剂过硫酸铵(APS)、功能单体MAA和交联单体DVB的浓度对聚合反应的影响。红外光谱结果证明发生了共聚反应。扫描电镜(SEM)和激光粒度仪观察到聚合物微球最小粒径小于50 nm。当反应温度、功能单体MAA和引发剂APS浓度增加时,单体的转化率也随之增加。反应温度为60 ℃、70 ℃、80 ℃时,反应4 h后单体转化率分别达到82%、89%和96%。
Abstract:
Styrene(St), methacrylic acid(MAA)and divinylbenzene(DVB)were copolymerized by using diffusion-controlled emulsion polymerization method without any surfactant, giving birth to polymer nanoparticles with clean surface. The FT-IR results proved the occurence of copolymerization reaction. The minimum diameter of those copolymer nanoparticles were monitored by SEM and laser granulometry could be less than 50nm. The influences of the polymerization temperature, initiator ammonium persulfate(APS)concentration, functional monomer MAA concentration, and crosslinking monomer DVB concentration were studied. It was found that as the reaction temperature, functional monomer MAA and initiator APS concentration increased, the monomer conversion also increased. When the reaction temperature were at 60℃, 70℃, and 80℃, the monomer conversion achieved 82%, 89% and 96% in 4h, respectively.
